The dropdown box is rendered in a different pane (the glass pane?) than the
rest of the ui. Therefore it needs to live under a container that has such a
pane, i.e. something that has a JRootPane such as JWindow, JFrame, JDialog.
If the top level container is not one of these, the dropdown list of the
JComboBox will not show up.
